Sponsor's own description

The evaluation of protein quality has top priority according to Food and Agricultural Organization of the United Nations. However, one aspect of protein quality, namely the digestibility of protein is largely unknown. A database on this matter is lacking as it is difficult to measure ileal digestibility in humans.
